Selecting all worksheets and entering text into a cell has the consequence
that the text will show on each worksheet in the same cell. However, it is
not linked. So if changes are made in this cell it only changes the current
worksheet.

I know the option of using "=" however, that would mean I have to link the
cell e.g. n all 20 sheets. It would be cool to use the option described above
only that the infos are also linked at the same time.

Does anyone know how to?

Kind regards
